Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/11243504
Curator's Comment: description was created based on several sources, including http://www.accessdata.fda.gov/drugsatfda_docs/label/2014/021165s017,021300s014,021312s015,021563s003lbl.pdf

Desloratadine is an active, descarboethoxy metabolite of loratadine. It acts by selective inhibition of H1 histamine receptor and thus provides relief to patients with allergic rhinitis and chronic idiopathic urticaria. Desloratadine was approved by FDA and it is currently marketed under the name Clarinex (among the others).
